oil pressure is about 40psi until it warms up and when it's warmed up pressure drops when idling but at about 1500 rpms it rises back up to 15 - 20 psi. has anyone run across this problem?
Uhhh, YES!unrestricted817 said:oil pressure is about 40psi until it warms up and when it's warmed up pressure drops when idling but at about 1500 rpms it rises back up to 15 - 20 psi. has anyone run across this problem?

UNCC_99XJ said:By running fine do you mean the computer gauge matched what the dash gauge was reading, or did the computer gauge read higher than the dash? If they matched, you have a problem, in which case it could be a couple of things, but more than likely a cracked head....this is if the two gauges matched.
If the computer one read higher, replace the oil pressure sensor. They're easy to replace, cheap enough, and very easy to damage when changing the oil.
Not saying for sure that's the problem. Given the information: a 2001, low oil pressure at idle, only 15-20psi. at 1500 rpm. Not saying that's 100% the problem, just trying suggest other areas to look at given that the 2000+'s are more prone to cracked heads, in addition to the common things like faulty sensors that could happen to any year, that's all.Ecomike said:How can you diagnose a cracked head from a single symptom, namely low oil pressure when hot at idle?
Please explain.old_man said:Number one question is......are you running a Fram oil filter?
